In the application note AN-234 it shows a circuit diagram with the outputs of the resolver directly connected to the AD2S90 chip. For the input to the resolver the circuit has a couple of op-amps on the input to the resolver (ref). The op-amps are both on a single US$3 AD712 chip.

The other thing that i thought would make this chip useful was the 1024 line incremental encoder emulation. Wouldn't this be able to feed directly to the encoder input on Paul's controller?
